Bad performance in Call of Duty using 4.12 Cats.

huang · Dec 19, 2004, 09:40 PM

I recently installed the official 4.12 cats and got very bad sporatic framerate drops in Call of Duty and United Offensive. My framerate would normally be locked at 75 (with vsync), but since installing the drivers it would drop into the 30s on certain maps (vanilla COD maps even), which is weird since the driver release notes mention a 5-6% improvement in COD. For the record here are my specs:

2.8C P4
512MB PC3200 DDR
Radeon 9800 Pro
120GB 7200RPM Hard Drive
Soundblaster Audigy 2 Zs

I rolled back to the omega 2.5.90 drivers and everything is back to normal. Can anyone else confirm that this is an issue with the 4.12 drivers?

I also took an FPS hit with the official catalyst 4.12's. The 4.10's were great with framerates but had the problem with causing the game to freeze. I also installed the new CODUO patch which was supposed to help with performace I thought but it seemed to either stay the same or even decrease some from what I could tell. I just don't think ATI has been focusing that much on getting their drivers to work with UO right now. Hopefully will improve in the future.

You might be able to get 4.10 drivers to work with CODUO if you update Punkbuster. There's some tool you can run from the pb directory under where COD is installed which'll update things and should keep you from being booted/frozen by PB.

I think the other issue is that COD is an OpenGL game, right? I get the impression that it's hard for ATI to improve the OpenGL performance by all that much without making some big changes, probably some bottlebeck within the Cat 4.x driver design. Let's look forward to better OpenGL with Cat 5.x. It's not as if stock OpenGL performs bad, it's more like the performance hit you get by turning on AA+aniso hurts OpenGL a lot more than you see with D3D.

I'd rather run a game in a higher resolution than turn on AA, at least 2x AA. 2x makes things too blurry, and 4xAA+16x aniso shows a pretty big hit at 1280x1024, but 4xAA + 8x aniso has been working really well for a buncha programs.

I'm not sure what the deal is with the game. I wish there was a set of drivers from ATI that were dedicated openGL so we'd get some better performance. After playing on some different servers, the 4.12 officials do seem to be giving me a steady 85FPS, except in some heavy battles. Weird thing is, in those maps where there were the big frame drops, those same areas seem to have gotten worse instead of better. Also when the vehicles are in use I'm getting a big frame per second hit. Maybe the servers just havn't been tweaked yet. I'm also hoping the map patch will fix some of the maps, hopefully. Oh my specs:

P4 2.26ghz
1 gig PC800 RDRAM
Intel 850emv2
ATI Radeon 9800 Pro 256mb
40 GIG 7200 Seagate
SB Audigy 2 ZS
Windows XP sp2
